What is Parkinson’s Disease?
Parkinson’s disease (PD) is a progressive neurological disorder that primarily affects movement. Currently, an estimated 84,000 Canadians aged 40 or older have been diagnosed with the condition.
Parkinson’s occurs when certain nerve cells in the brain begin to deteriorate. These cells produce dopamine, a chemical that affects mood regulation, memory, and movement. The loss of dopamine leads to various symptoms, most of which involve difficulties coordinating and controlling body movements.
However, Parkinson’s disease can also cause non-motor symptoms, such as mood disorders, loss of smell, or sleep disruption. In some cases, these symptoms begin to appear well before the movement symptoms, such as tremors or balance issues, that Parkinson’s disease is known for.
No two people will experience Parkinson’s disease in the same way. It’s also important to remember that the condition develops gradually over time. In fact, it has five distinct stages, each with its own set of signs and symptoms.
Early intervention is crucial in successfully managing Parkinson’s disease. If you or a loved one is showing any signs of the condition, it’s important to seek medical attention to begin treatment right away. Physiotherapy at (practice name) will also play an important role in managing your condition.
The Five Stages of Parkinson’s Disease
Stage One
Stage one symptoms are mild and may go unnoticed. Most individuals can continue their daily activities without major disruptions.
Select Stage One Symptoms
- Tremors in one hand while at rest
- Slight changes in posture or gait
- Mild stiffness in one arm or leg
- Changes in handwriting (often smaller or more cramped)
Stage Two
As Parkinson’s disease progresses to Stage Two, symptoms become more noticeable and affect both sides of the body. While individuals can still manage daily activities, tasks may take longer and require some assistance.
Select Stage Two Symptoms
- Tremors or shaking in both hands
- Increased stiffness in the arms, legs, and neck
- Slowness of movement that interferes with daily tasks
- Balance issues that can lead to a higher risk of falls
- Difficulty with fine motor skills (such as writing or buttoning up clothes)
Stage Three
Stage Three is considered the mid-stage of Parkinson’s disease. Symptoms are now more severe, and balance becomes significantly affected. Many individuals may experience regular difficulties with daily tasks and may require assistance.
Select Stage Three Symptoms
- Noticeable slowing of movements
- Increased fall risk due to increasing balance issues
- Difficulty standing up from a seated position
- Reduced ability to perform everyday activities without help
- Fatigue and a general sense of weakness
Stage Four
At this advanced stage, symptoms are severe, and individuals often need assistance with most daily activities. Mobility becomes highly limited, and many people may require help to live independently.
Select Stage Four Symptoms
- Inability to walk or stand without a mobility aid (such as a walker or cane)
- Severe stiffness and rigidity in the muscles
- Difficulty with basic daily tasks, such as dressing or eating
- Possible cognitive changes, such as memory problems
- Changes in sleep patterns and increased fatigue
Stage Five
Stage Five represents the most advanced stage of Parkinson’s disease. Individuals may be unable to stand or walk independently and often require full-time care. Communication and cognitive functions may also decline, necessitating comprehensive support.
Select Stage Five Symptoms
- Inability to walk or move without assistance
- Severe cognitive decline or dementia
- Difficulty swallowing, which can lead to choking hazards
- Increased risk of complications from immobility (such as pressure sores)
- The need for around-the-clock care from family or professional caregivers
Factors in Developing Parkinson’s Disease
Researchers do not currently understand why some people develop the neurological degeneration that leads to Parkinson’s disease. However, they have identified some contributing factors, although it’s important to remember that not everyone with these risk factors will develop the condition:
Age
- Age is perhaps the most significant contributing factor, as Parkinson’s disease is more common in older adults. It typically affects those 60 years or older.
Gender
- Research shows men are more likely to develop Parkinson’s than women, although either gender can develop it.
Genetics
- Family history can increase the risk of developing Parkinson’s, and certain genetic mutations are linked to the disease.
Environmental Factors
- Exposure to certain toxins, such as pesticides and heavy metals, may increase your risk.
Autoimmune Factors
- Some research suggests that autoimmune responses, where the body’s immune system attacks its own cells, may play a role in Parkinson’s disease.
Diagnosing Parkinson’s Disease
Diagnosing Parkinson’s disease can be challenging, as currently, there is no specific test to confirm the disease. Healthcare providers typically rely on a combination of the following:
Medical History
- A physician will ask about symptoms, family history, and any exposure to toxins.
Physical Examination
- A healthcare provider, such as a physiotherapist, will evaluate movement, balance, and coordination.
Neurological Assessment
- A neurological assessment is generally included in the physical exam. Tests may include checking reflexes, muscle strength, and gait.
Medical Testing
- Physicians may sometimes recommend brain imaging tests, like an MRI or CT scan, to rule out other conditions.
Treating Parkinson’s Disease
We currently do not have a cure for Parkinson’s disease. However, both medical and rehabilitative treatment options slow the disease process and alleviate symptoms. A multidisciplinary approach is essential when managing Parkinson’s disease.
Medications
Several medications are available to help manage symptoms by increasing dopamine levels or mimicking its effects. However, it’s important to recognize that these medications do not reverse Parkinson’s disease or stop it from progressing. Here are some of the options:
Levodopa
- This is the most effective treatment for rigidity and slowness of movement. It converts to dopamine in the brain. However, it does lose its effectiveness over time and is often combined with another medication, carbidopa.
Dopamine Agonists
- These medications mimic dopamine’s effects and can help reduce symptoms.
MAO-B Inhibitors
- These medications prevent the breakdown of dopamine in the brain.
Therapeutic Exercise
Following a Parkinson’s-specific exercise program is essential in managing the disease, and providing the specific exercises and guidance necessary for a program is one of the primary functions of physiotherapy treatment for Parkinson’s disease.
There’s evidence to suggest that beginning an exercise program in the early stages of Parkinson’s disease can slow down its progression. Furthermore, targeted exercises can help you maintain strength, mobility, and balance. And finally, exercise can enhance mood and cognitive function.
The Momentum Health physiotherapists will work with you to develop an appropriate exercise program for your needs. We’ll help you find exercises you enjoy and ensure they meet your ability levels.
Generally, therapeutic exercise programs for Parkinson’s disease will include the following:
Aerobic Exercise
- Aerobic exercise helps improve cardiovascular health, but for people with Parkinson’s, it can also slow down the degeneration of motor skills and protect against depression and other mood disorders.
Strength Training
- Strength training builds muscle and can help address the slowness of movement. In particular, lower-body and core strength training can help with balance issues.
Balance Training
- Balance training is essential in helping reduce fall risk. We’ll guide you through progressive balance challenges and work with you to address any postural or gait issues that might impact your balance and stability.
Why a Multidisciplinary Approach is Important
Managing Parkinson’s disease often requires a team of healthcare professionals, including physicians, physiotherapists, occupational therapists, and speech therapists. This collaboration ensures all aspects of the condition are addressed.
For example, physiotherapy helps individuals manage the motor symptoms and balance difficulties caused by the condition. Speech therapists can address communication and swallowing difficulties, while occupational therapists help individuals develop strategies for completing daily tasks like cooking, cleaning, or self-care.
Combining these therapies offers a comprehensive approach to treatment, allowing individuals with Parkinson’s to maintain independence and improve their quality of life.
